Gland condenser skid systems by direct contact heat exchanger technology

Abstract

The disclosure concerns a gland condenser skid system comprising a direct contact heat exchanger as gland condenser, configured to collect and condensate steam coming from a steam turbine sealing system, wherein the steam turbine sealing system is provided with an air buffering seal device, separating steam turbine shaft lubricating oil system from the steam turbine sealing system.

The invention claimed is: 
     
       1. A gland condenser system comprising a direct contact heat exchanger, configured to collect and condensate steam coming from a steam turbine sealing system, wherein the direct contact heat exchanger is a cylindrical column with a vertical axis, comprising an inlet for an air and steam mix flow from the steam turbine sealing system, in the lower part of the column and an inlet for cooling water at the top of the column, a condensate outlet at the bottom of the column and a residual steam and air outlet in the upper part of the column. 
     
     
       2. The gland condenser skid system according to  claim 1 , wherein the inlet for cooling water is provided with a spray nozzle. 
     
     
       3. The gland condenser skid system according to  claim 1 , wherein the residual steam and air outlet is connected to an evacuation device, configured as a vacuum generator. 
     
     
       4. The gland condenser skid system according to  claim 3 , wherein the evacuation device is a Venturi steam-operated pump fed by motive steam from a steam inlet. 
     
     
       5. The gland condenser skid system according to  claim 3 , wherein the evacuation device is connected downstream to a silencer.
